Darts don't require or necessarily use a water bowl for soaking like some other frogs do, or even need a waterway, although a lot of us set up vivariums for them with waterfalls, streams, drip walls, or even paludariums with aquarium sections. While they can swim, they are not deliberately aquatic. Generally speaking, they do require humidity above 80%, misting of some sort (depending upon your set-up), and generally temperatures from 65 at night to 80 during the day. It does depend a bit upon the species, of course, and whether you are breeding them or not.
Fruit flies are the easiest and most commonly used staple diet, but you can certainly use pin head crickets (the smallest), springtails, rice worms and some field plankton(insects collected in a pesticide-free place, including spiderlings, leaf hoppers, various gnats, aphids, etc.)
You can do a lot of searches on the various forums, contact some dealers such as Saurian, Black Jungle, Ed's Fly Meat, all of whom advertise here, and read their care sheets on the various dart frogs they have available. I'd suggest investing in one book in particular, "Poison Frogs," Professional Breeders Series, W. Schmidt. E.W. Henkel. I know that Black Jungle carries this. It costs about $35.00, and is one of the best small "how-to's" so far, with different species information and terraruim information for some useful ideas.
I apologize for the slow response. My own excuse is "last minute tax time."
They truly aren't all difficult to keep once you have the right conditions. Be sure to post back with more specific questions if you run into problems.
